I don't like the event->ignore() line of yours. Don't you think you should ignore an event if and only if both your handler and the base handler wants to ignore the event? It might be that the default handler accepts the event, but it gets ignored because you ignore it as it was not caused by right click and because of that Something Bad Happens. I don't know if that is the source of your problem (I doubt it), but you should double check that anyway. Despite that I think your item's handler should be getting called... Try extracting the smallest possible chunk of code that reproduces the problem.
